I'm evaluating an upgrade to the latest 2014 Q1 libs for the ASP.NET Ajax controls. I get this javascript error in both IE11 and Chrome. I've got a lot of stuff going on on this page, RadTreeViewControl, RadSpliter, RadGrid, RadTimePicker, RadScriptManager, RadAjaxManager, etc... I thoughtab I'd post this and see if I can get lucky about finding a solution before stripping the page down to figure out what's going on. This error occurs when I click on an item in the RadTreeViewControl.

Hello Mark,
Thank you for contacting us.
It is possible that the error you are observing is due to a commented lines within the head tag of your page. Following is very simple scenario replicating the same error:
The issue is due to the fact that during an ajax request the content of the head tag is also updated and returned in the request response which the browser is trying to parse but fails.
What I could suggest is that you either remove those commented lines or set the EnablePageHeadUpdate property of your RadAjaxPanel/RadAjaxManager to false.
Please give this a try and let me know if it solves the issue on your end.

Konstantin,
Your post here got me looking in the head tag which is in my Master Page which I had not changed for some time. When I removed some VML settings the issue went away. Thanks for your attention.
